Lübeck/Germany, 10.9.2024 – Newly founded joint venture TESVOLT OCEAN has introduced a battery system at the SMM trade fair in Hamburg that will enable significantly more vessels in the maritime and inland shipping industry to be equipped with clean e-drives for the first time. The system’s battery modules can be installed individually and at any angle of inclination, wherever there is space for them in the ship. The vibration-resistant storage modules can also be installed on the floor and walked on. Ships have often not had enough space for battery storage systems with sufficient capacity, until now. The new “Kaptein Series” power storage system features further unique characteristics, as a result of its disruptive technology: from the lightest weight to the highest energy density to the fastest charging capability. TESVOLT OCEAN also offers the entire solution lifecycle from a single source: from project planning, installation and services to the return of the battery modules, making clean e-drives for shipping more convenient and cost-efficient.

Longest range and fastest charging

“We’re entering the market with a best-in-class storage system, offering a technological solution for the biggest pain points of ship owners, system integrators, and shipyards,” explained Kent Thoresen, CTO of TESVOLT OCEAN. “The range of ships with electric propulsion, for instance, is still a problem for many owners. Ship spaces are often cramped, so not enough battery modules can be accommodated to achieve the desired range. At 246 Wh per liter, our new Kaptein system has the highest energy density on the market to date, meaning despite its high capacity it takes up very little space.”

Most batteries approved for use in shipping did not even have a continuous C-rate of 2 C. At 4 C, the “Kaptein” storage system offers the highest continuous C-rate available in the maritime industry to date. This means significantly shorter charging times for ship owners.

Light, safe, and individually installable

The new storage system also scores highly in terms of weight. At just 4.83 kg per kWh of storage capacity, it will be the lightest battery system for shipping on the market; batteries currently available on the market weigh at least 7 kg per kWh. A unique fire suppression system ensures maximum safety.

“We spent three years speaking intensively with customers in six focus groups about what they need. That's why Kaptein fits their needs so well. It solves real problems in e-propulsion for ships,” added Kilian Hoffmann, CCO at TESVOLT OCEAN. “We've already had a huge number of inquiries about the new battery system.”

Support right from the start

“Every customer has different goals. That's why we always tailor our battery system precisely to the individual customer. Kaptein is not an off-the-shelf product. But due to its special cell-to-module design, it’s exceptionally cost-efficient compared to the rest of the market,” said Øystein Kjæreng, CEO von TESVOLT OCEAN. “We’re a one-stop shop, offering planning, installation, and commissioning as well as monitoring, maintenance, and recycling. We want to make a significant contribution with this new product toward accelerating the equipping of shipping with clean e-drives — as simply and cost-effectively as possible.”

TESVOLT OCEAN is a joint venture between the two maritime industry experts, TESVOLT Maritime Solutions from Germany and Ocean Batteries from Norway. Based in Lübeck, Germany, the company develops high-performance battery storage solutions that are specially designed for the demanding conditions at sea. With its innovative products and solid services, TESVOLT OCEAN is setting new standards in Europe's maritime energy supply.
